Cannabinol, a pharmaceutically interesting component of cannabis, was prepared by a modified Ullmann–Ziegler cross-coupling. Using easily obtainable starting materials, this convergent approach allows facile access to a variety of cannabinol derivatives.
substrates represents a major challenge of the present cross‐coupling methodology. The nickel‐catalyzed Kumada cross‐ coupling of tertiary alkyl Grignard reagents with arylbromides allows this difficult reaction with numerous different substrates. Optimal results were obtained using sterically demanding, bifunctional N‐heterocyclic carbene ligands.
